Definitions
- Test specimen for ultrasonic testing The invention relates to a test specimen for ultrasonic testing with a test error or reflector of a certain type, position and size, for testing or calibrating (calibrating) ultrasonic test devices or test heads.
- the invention is intended for use in non-destructive material testing.
- Test reflectors or small test errors are required to calibrate ultrasound test devices and / or test heads and to prove fault detection.
- Circular disc reflectors in the form of blind holes with a flat bottom.
- such holes cannot be made as small as desired, especially if the floor is to be flat.
- the object of the invention is to reproducibly produce a test specimen with a very small test error in ⁇ 0.5 mm in position and sound behavior. Furthermore, the test specimen should be easy to manufacture and contain a reflector with any, but reproducible shape. This task is solved by the features of the main claim. Further features of the invention are contained in subclaims.
- the invention makes it possible to produce a test specimen with reproducible replacement errors and / or replacement reflectors (inserts) of the order of magnitude of approximately 0.01 to 0.05 mm, which are defined geometrically within narrow limits. Furthermore, the invention enables the reflector to be produced in almost any reproducible form and to determine the associated influences on the ultrasonic signal.
- the test specimen consists of powderable metal, intermetallic phases or ceramics.
- the inserts advantageously consist of quartz glass or a similarly behaving material.
- Fig. 1 shows the test specimen with the insert arranged therein
- Fig. 2 shows the detail A. Fig. 1 in an enlarged view.
- the test specimen 1 - here a pressed body - is contained in a capsule 2.
- This has a filling tube 3; Grain ⁇ 100 ⁇ m, an intermetallic phase or a ceramic powder is advantageously filled into the metal powder, for example Ni-based alloy.
- the filling tube is removed together with the cover after the pressing process (hot or cold isostatic), for example ground off. The ground surface then forms the later specimen surface 4.
- an insert holder 5 and an insert 6, for example a quartz rod are attached in the bottom area of the compact 1 .
- the insert has, for example, a reflector surface 7 lying in a plane parallel to the specimen surface 4. With the help of this replacement reflector or replacement error, the desired tests can be carried out on ultrasonic devices.
- the direction of insonification is from top to bottom, ie in the vertical plane or in planes parallel to the axis of the compact.
- the test specimen is usually immersed in a liquid.
- the insert (s) 6 made of material that does not interfere with the ultrasonic testing, such as quartz glass or synthetic diamond, sapphire in the form of a rod, needle or fiber, of approximately 10-100 ⁇ m in pieces or particulate with any surface formation (see FIG. 3) is in a defined geometric position ( 1) held in the (Fe) capsule by means of the holder 5 on the bottom thereof, for example at a distance of 1 - 10 mm from 4, if the capsule is about 20 mm ⁇ and about 30 - 60 mm long.
- material that does not interfere with the ultrasonic testing such as quartz glass or synthetic diamond, sapphire in the form of a rod, needle or fiber, of approximately 10-100 ⁇ m in pieces or particulate with any surface formation (see FIG. 3) is in a defined geometric position ( 1) held in the (Fe) capsule by means of the holder 5 on the bottom thereof, for example at a distance of 1 - 10 mm from 4, if the capsule is about 20 mm ⁇ and about 30 - 60 mm long
- the metal powder is then introduced through the filling tube or a filling funnel.
- the mounting of the inserts such as quartz rods on the capsule, in particular on the capsule base is designed - advantageously conical - that no one-sided forces during the pressing process, e.g. Apply cold or hot isostatic pressing to the insert, such as a quartz rod.
- the capsule is advantageously evacuated during the filling process of the capsule with the powder material, after which it is closed, for example if the capsule is made of metal Weld so that it is tight.
- the powder can also be filled in under air and then - just before sealing - evacuated. Then the pressing process is started. It can be carried out in a press customary for the processes mentioned, at the usual pressures and temperatures. In addition, one or more heat treatment stages can follow the pressing process.
- the encapsulation is then carried out by cutting off the filling tube with the lid.
- the nominal length is set at 4 by a processing method known per se.
- the insert must be tightly enclosed.
- the test specimen consists of a material that is the same or similar to the material or workpiece to be tested. It is necessary to use materials or groups of materials that can be processed using a powder metallurgical process.
- HIP hot isostat presses
- Quartz is suitable for use in nickel-based alloys because, e.g. when hot pressing, can be used well. At the HIP temperature for such an alloy, the use is so firm that the shape is retained and there is a sufficient impedance difference to the surrounding material from the alloy.
- other correspondingly suitable material combinations can also be selected.
- a high-resolution test head of appropriate wavelength in relation to the desired resolution is preferred and corresponding power, for example between about 5 and 50 MHz, in particular 25 MHz.
- the test head not shown, is brought into contact with the surface 4 of the immersed test specimen 1 that has been ground to the last dimension (desired length).
